After the passing of the Air Canada Act in 1978, Air Canadien became able to more fully compete with Air Canada, which led to the opening of many new domestic routes from both Montreal and Quebec City. The same year, a new brand identity - dubbed 'Fierté du Canada' - was introduced on the newly acquired DC-8-63. In 1980, Douglas DC-9-30 and -50 aircraft were received by the airline to facilitate further expansion on routes the small Fokker F28 jets and old Comet 4Cs were not as well suited for. The same year saw Air Canadien operate its first international flight, when a DC-8-63 registered C-CPKB operated flight 3202 from Quebec City to New York JFK (the flight would later be operated by a DC-9-50). DC-8s and DC-9s would fly all routes into the United States in the first few years of international operations. The third aircraft type acquired in 1980 was the DC-10-40. Air Canadien opted for the Pratt & Whitney JT9D-powered 40-series due to its close relationship with PW, which supplied engines for all Douglas aircraft in the fleet. These DC-10s would operate flagship routes to Europe (and later some to Asia), but it soon became apparent that a smaller widebody was necessary for lower-demand destinations. While Air Canadien placed orders for Boeing's upcoming 767 late in 1980, in 1981 a purchase of eight used Airbus A300B4s (also powered by the JT9D) was made from a German carrier. These were the only Airbus aircraft Air Canadien would operate. While the DC-10-40 fleet would grow to include over twenty aircraft at its peak, only eight A300B4s would ever be flown by the airline.
